VGSCAN(8) System Manager's Manual VGSCAN(8)NAME
vgscan - scan all disks for volume groups and rebuild caches
SYNOPSIS
vgscan [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes] [-P|--partial] [-v|--verbose]
DESCRIPTION
vgscan scans all SCSI, (E)IDE disks, multiple devices and a bunch of other disk devices in the system looking for LVM physical volumes and
volume groups. Define a filter in lvm.conf(5) to restrict the scan to avoid a CD ROM, for example.
In LVM2, vgscans take place automatically; but you might still need to run one explicitly after changing hardware.
OPTIONS
See lvm for common options.
--mknodes
Also checks the LVM special files in /dev that are needed for active logical volumes and creates any missing ones and removes unused
ones.

Sorry for the noob question; my experience is with Solaris.
Am I reading this right? Are these disks completely unused? Not possibly raw disks for informix or something?

Hi,
I'm getting the errors below in the errpt report for a IBM Blade server. I'm guessing there's a problem with one of the disks but don't know how I can confirm this. Can anyone offer any suggestions?

Hi, First post. I am not to experienced in the Unix or HP-UX world but I'm learning.

Hi guys,

I am about to retire several servers and need to delete the company confidential data from the internal disks under LVM control. Is there a proven and easy way to accomplish this ?
Thanks for all the help in advance. (4 Replies)
Have you ever had a need to know which lvols were on which disks? Maybe you needed to expand an index filesystem and wanted to make sure you did not expand onto a disk with a data filesystem. Here is a script to see how each lvol is laid out on each disk. (For VGs with many PVs it may be easier to... (3 Replies)

I picked up a V440 and it has 4 disks. I installed Solaris fine to disk 3, but I cannot see the other disks in Solaris.
I have run probe-scsi-all from OBP and I see the other disks and they have names in devalias AFAIK. It's just in Solaris they do not appear. I have run... (6 Replies)

Scenario1:
VG00 lvm,not mirrored,2 disk of 36GB vg size
VG00 size is under 30G.
Is possible to remove a disk of 36GB and replace "on fly"
with a disk of 300GB on VG00?
Thanks (6 Replies)
Hi Guys,
Looking for advice really this time, I have just completed building a server. As it was a fresh build and was just a standard RHEL 6.6 server which would run TSM I just went for partitioning up the disks as I built it.
The disks are 3 500Gb disks in a RAID5 configuration giving just... (5 Replies)

In principle it is possible to create FSes on shared volume groups with cluster methods (also known as C-SPOC), either from the command line or using the respective SMIT menus. In practice, however, many options are missing in the C-SPOC variants. For instance, it is not possible to add a... (6 Replies)
I am running an automated microscope (LIBRA) on SCO openserver.
I would like to set up the system on younger hardware but I am missing installation disks for acceleratedX (X inside inc).
Can anyone provide the disk contents ?
Thanks a lot! (9 Replies)
